Countermeasures to Impacts of Bandwidth and Receiving Buffer on CMT Schemes

Abstract Based on the impact investigation of both bandwidth and receiving buffer on concurrent multi-path transmission (CMT) schemes of Stream Control Transmission Protocol (SCTP), the authors present an adaptive policy on how to effectively apply CMT-SCTP schemes under various network conditions. Moreover, an optimal fast SACK (FACK) scheme is proposed too in this paper in order to accelerate the feedback of SACKs and further find out varieties of both available bandwidth and loss rate as soon as possible. Simulation results show that the proposed scheme could improve the traffic efficiency of the CMT scheme when receiving buffer is bounded and network bandwidth gets smaller
